IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 30,235. dated October2, 1860.

`useful Improvement inthe Construction of the Frame of theHarvesting-Machine invented and patented by the late John H. Manny, ofwhich the following is a full, clear, and exact descrcription, referencebeing had to the accompanying drawings, which make part of thisspecification, and in which* Figure I represents a view in perspectiveof the frame of a .I. H. Manny harvestingmachine,77 and Fig. II asimilar view of the same with. myimprovement applied thereto.

In the machine invented and patented by the late John II. Manny, andknown as the John H. Manny Harvesting-Machine,77 the frame-ti1nbersproject so far back of the axis of oscillation of the machine that whenthe linger-beam is raised to any considerable height from the ground,(as it must necessarily be in cutting tall and heavy grain) the saidprojection is very liable to strike or drag upon the ground when thewheels sink into a furrow or gully. This not only causes shocks andjars, which are very injurious to the mechanism and dangerous to theattendants or operators, but also causes the machine to drag veryheavily upon the team.

It is the object of my invention to remedy the above-mentioned amongother defects incident to this mode of constructing the frame 5 and tothis end my invention consists in so arranging the frame-timbers uponwhich the platform rests with respect to the finger-beam and main frameas very materially to diminish the distance between the front and rearof the frame, by which means I am enabled to elevate the cuttingapparatus to any height required in practice without danger of back partof the machine touching the ground, while I retain the necessary widthof platform for the perfect operation of the machine. This arrangementalso enables me to brace the side piece which supports the bearing ofthe grain-wheel at the point at which it is exposed to the greateststrains, and thus to` increase the rigidity of the frame, while Idispense with one of the braces necessary to the invention on which myown is an improve ment.

In the accompanying drawings, the lingerbeam F is represented asbeing-secured to the main or gearing frame E at right angles thereto, inthe same manner as'heretofore. Instead of a long longitudinal side pieceextending backward from the divider or grain end of the finger-beam atan angle of about sixty degrees thereto, and uniting with a similarpiece extending from the stubble end of the finger-beam, as hasheretofore been the case, I employ a short side piece, b, secured firmlyto the inger-beam F at the divider end thereof, and" projecting at rightangles, or thereabout, therefrom. The rear end of this side piece issecured to one end of the rear cross-piece, c, the other end of which isfastened to the rear end of the main frame. A brace d, extends backwardfrom about the middle of the side piece, b, at an angle of aboutforty-five degrees thereto, and its rear end is bolted to the rear endof a similar brace a, extending backward at a similar angle to thefinger-beam, the front end of which brace is secured to the main frameE. The braces a al are also fastened to the side piece c at their pointsof intersection, one brace, cl, passing above the cross-piece c, whilethe other, a, passes below it, one being mortised on its upper, the'other onits under, side, that they may touch each other at their extremerear ends, to increase the rigidity of the frame. By this method ofconstruction I not only strengthen the frame tothe utmost capacity ofthe material employed, but I also simplify its construction a anddispense with one of the braces necessary to the old mode. The brace-bard, being secured to the side piece b just at the point where the bearingfor the support of the grainwheel is'attached, strengthens the framevery materially, as this is the very point most liable to twist andstrain when the machine is running over uneven ground.

Fig. 1 represents a view ofthe J. H. Manny machine as heretoforeconstructed, and both figures being drawn on the same scale, thedifference in the arrangement of the frametimbers and the dista-nce towhich they re= speetiv'ely project behind the. axis of oseillal Intestimony whereofl I have hereunto `subtion can readily be seen. scribedmy name.

Vhat I claim as my invention, and desire to secure by Letters Patent,is- FREDERICK H. MANNY.

The arrangement of the beams a b c d relatively to the finger-beam andthe main frame Vitnesses: and to each other, substantially as herein de-JOHN P. MANNY, scribed7 for the purpose set forth. V. C. BLINN.
